Oscilloscopes, also called Digital Storage Oscilloscopes (DSOs) or Mixed Signal Oscilloscopes (MSOs), are a common type of test instrument used to capture, analyze, and troubleshoot electrical or real world physical signals. Oscilloscopes observe the change of electrical signals over time, continuously graphed on a display as voltage or amplitude vs. time. During observation, oscilloscopes can analyze waveforms parametrically (i.e. frequency, RMS, peak-to-peak amplitude, rise time, etc.) Non-electrical signals, especially mechatronic signals such as vibration, strain, temperature, or current can be converted to voltages and displayed.

Yokogawa oscilloscopes deliver a range of bandwidths, the world's only eight channel and sixteen channel (plus logic) oscilloscopes, unparalleled suites of triggers and signal analysis, and a unique ability to save multiple triggered-events to "History" memory.

Xviewer (701992) / XviewerLITE Software

Xviewer is a PC software application designed to work with Yokogawa's DL series digital oscilloscopes and the DL850 series/SL1400 ScopeCorders. Xviewer allows you to display DL-acquired waveform (using the "Viewer" function), perform file transfers, and control DL series instruments remotely. Free version, XviewerLITE is also avaiable.


XWirepuller is a free software enables you to display the front panel of the DLM/DL/SL/WT series on the screen of a PC, and monitor waveform signals. You can perform control from the PC using the mouse and keyboard in the same way as you operate the main unit.

MATLAB WDF Access Toolbox

MATLAB WDF Access Toolbox enables the access to waveform data files saved in WDF format on MATLAB.

Symbol Editor

This software is for creating and editing physical value symbol definition files for serial bus analysis based on data below.

Mask Pattern Editor

This software program is used to create mask patterns that are used on the DLM4000 / DLM2000 / DL9000 / DLM6000 / DL6000 series and SB5000. The mask pattern created using this program can be loaded into the DLM4000 / DLM2000 / DL9000 / DLM6000 / DL6000 / SB5000 via a PC card or USB memory and used for mask tests, GO/NO-GO judgements, and history search.


DL-Term is a command line tool for the DL series library. Please use this software as a development tool for writing communication programs using the DL series library.

Binary Data File Converter

This tool enables you to convert a binary data file saved by DL or DLM series instruments with .wdf extension into binary data files with .wvf and .hdr extensions.

DL350 Assistant Software

This software can be utilized for ScopeCorder DL350 data and setup file management by a PC. Data files or setup configuration files stored in the DL350 SD card can be backed up with the press of a button. Remote setting, start-stop control and setup file editing can also be easily done on the connected PC.

WDF File Access Library

This software offers API (Application Program Interface) for acquiring data from waveform data files (WDF) saved on the measurement instrument.
